I have a 1996 150 Mariner (2.0) that is burning too much oil and having trouble cold starting. I think I may have caused it myself by putting a new fuel line on in reverse (real smart huh!). I primed the bulb several times which ended up sucking TCW3 through the pump and 2psi check valve. Then realized my stupid move and switched the hose around. To make matters worse, one of my equally absent minded fishing partners had knocked the arm off of the oil pump which meant that the outboard was being run with the oil pump maxed out for the next couple of fishing trips.<br /><br />Since then, my engine has failed to cold start on several trips. The plugs are always fouled with wet oil when I have trouble cold starting. I can get it running by cleaning the plugs or using ether (I know, bad move) but find that it is pushing plenty of smoke and plenty of unburned oil is hitting the water.<br /><br />Do any of you think that I've damaged the oil pump or the 2psi valve or both??? Or is the "wrong oil pump end plate" problem that ODDD1 has mentioned in the past a contributing factor?<br /><br />Please help?!
